hello all

I have faced a memory issue problem. I need some adivice to fix the follows error:

'' program will not fit into available memory. placement with alignment/blocking fails for section ".TI.ramfunc" size 0x1e41 page 0. Available memory ranges:''

MEMORY
{
PAGE 0 :
/* BEGIN is used for the "boot to SARAM" bootloader mode */

BEGIN : origin = 0x000000, length = 0x000002 /* Boot to M0 will go here */
RAMM0 : origin = 0x000050, length = 0x0003B0 //0x0003B0
RAML0 : origin = 0x008000, length = 0x001000
RAML1 : origin = 0x009000, length = 0x001000
RAML2 : origin = 0x00A000, length = 0x001000
RAML3 : origin = 0x00B000, length = 0x001000
ZONE7A : origin = 0x200000, length = 0x00FC00

....

}

SECTIONS
{
/* Setup for "boot to SARAM" mode:
The codestart section (found in DSP28_CodeStartBranch.asm)
re-directs execution to the start of user code. */
codestart : > BEGIN, PAGE = 0

#ifdef __TI_COMPILER_VERSION__
#if __TI_COMPILER_VERSION__ >= 15009000
.TI.ramfunc : {} > RAML0 , PAGE = 0
#else
ramfuncs : > RAML0, PAGE = 0
#endif
#endif

...

}

i have change

RAML0 : origin = 0x007000, length = 0x002000

it start debug but the

it says

'' one or more memory is not in the apprropraite loaction... "

thanks

Hi,

If you intended to combine L0 and L1 RAMs, I hope you removed/commented out the next line on L1 : RAML1 : origin = 0x009000, length = 0x001000

I thanks for your information. but RAML1 is already assigned for the following:
.text : > RAML1, PAGE = 0
IQmath : > RAML1, PAGE = 0

so i move .TI.ramfunc to RAML3 as follows

MEMORY
{
page = 0;
...
RAML3 : origin = 0x00B000, length = 0x002000
...
}

SECTIONS
{
#ifdef __TI_COMPILER_VERSION__
#if __TI_COMPILER_VERSION__ >= 15009000

.TI.ramfunc : {} > RAML3, PAGE = 0
#else
ramfuncs : > RAML0, PAGE = 0
#endif
#endif
...
}

Now it can run, but still i have the following message and warnings:

C28xx: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.

#10247-D null: creating output section "xxx" without a SECTIONS specification

so it needs further correction!

thank you

Hi,

While editing the cmd file, make sure not to disturb the MEMORY section. You could combine 2 RAMs if necessary, but make sure the start address and length are handled correctly.
